The former is going to be popular with commercial streaming services over the long haul, and the latter is Google's codec of choice for YouTube, which immediately unlocks a good deal of power savings. The GPU's media block received a significant overhaul, getting full hardware support for HEVC Main10 and the VP9 codec. Speaking of the integrated GPU, besides clockspeeds, this is the other area where the switch to Intel's Kaby Lake processors improves things for the Surface Pro. This provides yet another tier of memory before having to go to the (relatively) slow system memory, and depending on the application, can provide a real boost to performance.
The Iris Plus graphics configuration not only doubles the execution units available, from 24 to 48, but also includes 64 MB of eDRAM which can be used as a system cache as well as a graphics buffer. This adds another wrinkle over most other Ultrabooks in that it offers the Intel Iris Plus Graphics 640, compared to the HD 620 graphics in the i5 (and most other Ultrabooks) and the HD 615 graphics with the Core m3 model. Microsoft has provided the Core i7-7660U Surface Pro for review, with 16 GB of RAM and a 512 GB SSD. This will allow quite a bit more responsiveness from the system, as well as overall higher performance if the device can keep the heat and power consumption in check for more sustained boosting. You can see the base frequencies have all improved slightly, but the boost frequencies on all of the chips have increased significantly. Surface Pro 4 CPU vs Surface Pro (2017) CPU Even though the latest Kaby Lake chips utilize the same CPU architecture as Skylake, improvements to the 14 nm process, which Intel is calling 14nm+ allows for higher frequencies, and lower power consumption, so despite having the same architecture, there are gains to be had.
The choices are the same as the outgoing Pro 4, but one generation newer. The Surface Pro has always provided good performance for the size of the device, and for the new Surface Pro, we see the step to the latest 7 th generation Intel Core processors.
